improvement is fully set forth in the follow ing specification andaccompanying drawings.

My invention relates to registers or ventilators; and it consists in ,animproved con-f struction of indicatorplate or Wheel therefor i wherebythe opened or closed condition of the register'or yventila'mr may bereadilyiasvy certained, said plate havingopenings .therein and beingsupported upon the centerof the face-plate, said center`being.stationary and slotted or provided with openings to conform tothe slots or openingsv in said indicator-l center ,will readily indicatethe opened or` closed condition of the register.

The engagement of the lugs L with the arm M will cause the frame or barN to be reciprocated at the proper intervals, and by' reason of theintermediate connections the plates or blades S, T, and U are actuatedat the proper intervals, as is evident.

A designates a recess in that porti-on of the bar N which is contiguousto the boss B on the inner Surface of the indicating-wheel F, saidrecess being guided by said boss, which latter serves to limit themovementof the bar N, as is evident.

It will be evident that slight changes may be made by those skilled inthe artwhich will come within the scope of my invention, and I do nottherefore desire to be limited in every instance to the exactconstruction l -I claim as new, and desire to secure by Letters Patent,ism

l. The combination of a face-plate having a stationary slotted centralportion, an indicating wheel or plate rotatably mounted adjacent to saidface -plate, said indicatingplate being provided with solid and openportions respectively, which are adapted to be turned into and out ofalinement withthe openings through said face-plate andto thus indicatethe opened and closed condition of the register, a bar operated by saidwheel and having a recess, a boss on said Wheel engaging said recess,and operating connections between the bar and the register-shutters.

2. In a register or ventilator,.a face-plate, an indicating Wheel orplate mounted thereupon and provided with openand solid portionsrespectively, conforming to the open` and solid portions in thestationary central portion of said face-plate, lugs on saidindicating-Wheel, a bar suitably supported, a recess in said bar, yaboss on said Wheel engaging said recess an arm projecting from said barand engaged by said lugs, and shutters or detlectors actuated by saidbar.

3; In a register, a face-plate having a stationary central portion,andprovided with a series of slots, an indicating wheel orl platerotatably supported adjacent thereto andvprovided with a series ofslots, annular recesses in said face-plate and Wheel located inproximity to each other, a suitable spring seated in said recesses andadapted to prevent rattling and improper movement of the parts whenoperated, lugs on saidwheel, a bar having an arm engaging said lugs, arecess in said bar, a boss on said` Wheel engaging said recess, andshutters actuated by said bar.

4. In a register, a face-plate havinga stationary lcentral portionprovided Witha series of slots, an indicating wheel or plate rotatablysupported adjacent thereto and also provided with a series of slots,annular recesses in said face-plate and wheel located in proximity toeach other, a suitable spring seated in said recesses and adapted toprevent rattling and improper movement of the parts, lugs on said Wheel,a bar having an arm engaging said lugs, a recess in saidfbar, a boss onsaid Wheel engaging said recess, the terminus of the latter contactingwith said boss when said bar is in its extreme position, shuttersrotatably supported and connections common to said shutters and to saidbar.
